Unlike traditional cranksets, which need to accommodate rider weight and bottom bracket specs, e-bikes bring a new power source to bear on cranks. E-bikes’ unique demands for cranks that are durable without adding extra weight, yet are compatible with the bike’s power source, and consequently its warranty, suddenly require cranks with specific characteristics.

Next time you're shopping for an e-bike, to assure the bike's overall quality, look on the inside of the crank arm for Miranda's logo.
